Here's a really cool photo of guided-missile destroyer USS Ross ripping through the Mediterranean while under high wind conditions. To me, it looks like the warship has activated a force field around it and is impenetrable to everything. In reality, however, the destroyer is drenched.

A group of physics students from the University of Leicester have calculated that the laser-deflecting shields used by spaceships in Star Wars are not only theoretically feasible, but could also be constructed using today's technology.

Here's the video of the Airborne Ultrasound Tactile Display, one of those technologies that will probably change entertainment forever: A high-fidelity 3D force field on the air that allows you to actually touch virtual objects with your bare hands. Initially, this technology could find its way into virtual…

A group of British scientists are teaming up to create the first ever Star Trek-style force field. The shield would be used to protect astronauts from cancer-causing radiation coming from the sun in the form of solar wind. Astronauts will be able to turn the shield on or off, and they'll even be able to use it on…

Developed by various defense companies, the Trophy system is basically an active forcefield around a tank or an armored vehicle to defend against RPG rounds. It's not an actual forcefield like the USS Enterprise, it's a system that detects when a round is incoming and shoots out a projectile to eliminate the threat.…
